线性稳压器AP7381-50Y-13（美台Diodes）替代

东沃电子代理的TMP1202和TMP1203是款低压差线性稳压器，工作电压高达36V。查看东沃电子代理的TMP1202和TMP1203低压差线性稳压器产品手册可知，TMP1202/TMP1203 is a low-dropout linear regulator that is operating up to 36V. With only 65μA (typical) quiescent current at no load, TMP1202/TMP1203 is suitable for standby Microcontrol-Unit systems especially in automotive applications. TMP1202/TMP1203 has an integrated short-circuit and over-current protection function. TMP1202/TMP1203 operates over a -40°C to 125°C temperature range. Because of these features, the TMP1202/TMP120 is well suitable for power supplies for various automotive applications。关于TMP1202和TMP1203低压差线性稳压器，很多电子工程师并不熟悉，接下来专业代理商东沃电子（DOWOSEMI）从特性、引脚配置、应用三方面来了解TMP1202和TMP1203。
